In this project you will practice memory access optimization, performance-oriented programming, and OpenMP parallelizaton
|

on the ICS Cluster .

\section{Explaining Memory Hierarchies \punkte{25}}
|
||||||
|
|
||||||
|
By identifying the memory hierarchy parameters through \texttt{likwid-topology}
|
||||||
|
for the cache topology and \texttt{free -g} for the amount of primary memory I
|
||||||
|
find the following values:
|
||||||
|
|
||||||
|
\begin{center}
|
||||||
|
\begin{tabular}{llll}
|
||||||
|
Main memory & 62 GB \\
|
||||||
|
L3 cache & 25 MB per socket \\
|
||||||
|
L2 cache & 256 kB per core \\
|
||||||
|
L1 cache & 32 kB per core
|
||||||
|
\end{tabular}
|
||||||
|
\end{center}
|
||||||
|
|
||||||
|
All values are reported using base 2 IEC byte units. The cluster has 2 sockets
|
||||||
|
and a total of 20 cores (10 per socket). The cache topology diagram reported by
|
||||||
|
\texttt{likwid-topology -g} is the following:
